Sandy's Submarine is a large submarine that was first used by SpongeBob and Patrick to get the clarinet reed back out of Squidward. It has only had four appearances: "Squidtastic Voyage," "Hide and Then What Happens?," "Bubble Troubles," and "It Came from Goo Lagoon." At the end of "Squidtastic Voyage," Patrick accidentally turns the submarine back to large size and SpongeBob and Patrick are stuck in the submarine inside Squidward. In "Hide and Then What Happens?," the submarine looks very different. It may be a different submarine. SpongeBob used it to find Patrick. It's also seen in "Bubble Troubles," which Sandy used it to go to the surface to retrieve air. However, SpongeBob opened the hatch underwater, letting all the water in it, during which Sandy nearly suffocated. In the episode, "It Came from Goo Lagoon" Sandy, as well as Patrick and SpongeBob follow the goo bubble and find out what's causing it to move.
